Displaying webpage information of parent tab associated with new child tab on graphical user interface

ABSTRACT

A method and system. In response to receiving a click on a first link included in a parent webpage being displayed on a graphical user interface (GUI) on which a parent tab associated with the parent webpage is displayed: a new tab corresponding to the first link is created, the new tab is displayed on the GUI, the parent webpage is replaced by a new webpage associated with the first link, and a screenshot of the parent webpage is generated and saved to a tooltip attribute of the new tab. A cursor of a pointing device hovering above the new tab is detected. The screenshot is retrieved from the tooltip attribute and persistently displayed on the GUI. During displaying the screenshot and with the hovering above the new tab no longer occurring, a click on the screenshot is received and in response, the parent webpage in the GUI is reopened.

This application is a continuation application claiming priority to Ser. No. 14/948,478, filed Nov. 23, 2015.

TECHNICAL FIELD

The present invention relates to displaying webpage information of a parent tab associated with a new child tab on a graphical user interface.

BACKGROUND

Daily activities require a wide variety of information devices, such as mobile phones, personal computers, notebook computers, and tablets. Due to widespread network use, users use handy information devices with web browsers, such as Microsoft Internet Explorer®, Mozilla Firefox®, Apple Safari®, and Google Chrome®, to view text, images, and other multimedia information posted on one or more webpages. Basically, the web browsers each comprise a graphical user interface (GUI) for enabling a user to view multiple webpages in different windows and/or to launch on a single source page multiple webpages from multiple links. For instance, the user views a webpage by clicking one of a series of links on a resultant webpage found by a search, and then goes back to the resultant webpage, and subsequently clicks another different link on the resultant webpage to view other webpages.

In a tabbed web browser, multiple webpages are displayed within a single window in tabs. The user can view the tab only one by one. The tab is essentially for use in identifying a specific opened webpage. The user selects/identifies the tab of an opened webpage on a tabbed user interface and displays the webpage in the window. Hence, a selected tab related to a webpage being displayed in a window is called as an active tab, whereas one or more unselected tabs related to the other opened webpages not being displayed in the window are called as inactive tabs (i.e., hidden webpages).

The user usually launches a webpage by opening a link in a new tab provided by a resultant webpage, an index webpage, or any webpage having multiple links, which may be found by a search. As a result, after viewing the webpages of the new tabs, or after opening multiple new links among multiple new webpages provided by multiple identifiable new tabs from parent tabs, the user is likely to forget which link, in a webpage of a parent tab, has been clicked on for the purpose of the creation of the current new tabs.

However, the prior art fails to readily identify which link, in a webpage of a parent tab, the new tab is from. Moreover, in conventional tabbed web browsers, a title of a new tab often differs from a name of a link, as shown in the webpage of parent tab, for the creation of the new tab. As a result, in the webpage of parent tab, the user is unlikely to find the parent link which the new tab is from.

FIG. 1A illustrates a frame of a webpage on a conventional browser display interface, in accordance with the prior art.

Referring to FIG. 1A, a tabbed web browser 100 comprises a parent tab 102. Three links 114, 116, 118 in a webpage of the parent tab 102 have ever been clicked on for the creation of three new child tabs 104, 106, 108, respectively. However, tab titles of the three new child tabs 104, 106, 108 are different from names of the three links 114, 116, 118. For instance, the names of the three links 114, 116, 118 are “nine Practice”, “Security Resources”, and “Start Africa Course”, respectively, whereas the tab titles of the three new child tabs 104, 106, 108 are “IBM 1-3-9 Home”, “Security—Think Academy Wiki”, and “Think Academy Africa”, respectively.

FIG. 1B illustrates a tab bar and a tooltip 110 of a webpage on the conventional browser display interface, in accordance with the prior art. If a cursor 109 of a pointing device (e.g., a mouse) of a user hovers above the new tab, the tooltip 110 of the Uniform Resource Locator (URL) of a webpage which contains the tab title and/or new tab is presented to the user.

Known existing tab management technology presents to users the tabbed relationship between a parent tab and a new child tab, such as a plug-in of Mozilla Firefox®, and the tree hierarchy of the tabs provided by Tree Style Tab (tree diagram tab directory management).

SUMMARY

The method of the present invention provides that when a user clicks on a link in a parent webpage pf a parent tab and then creates a corresponding new child tab, a screen capture to the webpage of the parent tab is performed by triggering a snapshot mechanism, in such a way a screenshot is generated and at the same time the link being clicked is highlighted. By using a graphical reminder having the screenshot and the highlighted link, such as a tooltip, the user can easily backtrack a webpage of a parent tab (i.e., source webpage) and its related link. Even if the parent webpage of the parent tab has been closed, the parent webpage can be re-opened by clicking on the screenshot to load the parent URL.

In accordance with one embodiment of the present invention, the present invention provides a method for displaying webpage information of a parent tab associated with a new child tab on a graphical user interface, the method comprising the steps of: opening a link from a parent webpage of a parent tab for identifying a new tab of a new webpage; creating the new tab; recording a position of the link; capturing a screen of the parent webpage to generate a screenshot; highlighting the link in the screenshot; and saving the screen shot with the highlighted link to a tooltip attribute of the new tab.

The present invention also provides a computer program product stored in a computer-usable medium, the computer program product comprising a computer-readable program executable on a computer to implement the aforementioned methods.

In accordance with one another embodiment of the present invention, the present invention provides a computer system for displaying webpage information of a parent tab associated with a new child tab on a graphical user interface, the computer system comprising a host, the host comprising: a bus system; a memory connecting the bus system, wherein the memory includes a set of instructions; and a processing unit connecting the bus system, wherein the processing unit executes the set of instructions to implement the aforementioned method.

FIG. 2 to FIG. 5 show a flowchart and a block diagram of a practical architecture, functions and operations of a system, a method and a computer program product according to embodiments of the present invention. Each block in the flowchart or block diagram may represent a module, a segment or a part of a program code, and may include one or more executable instructions to perform a designated logic function. It should be noted that, in other embodiments, the functions depicted by the blocks may be performed in a sequence other than that shown in the figures. For example, two connected blocks in each figure may both be performed, or, with certain functions involved or under certain circumstances, may be performed in a reverse sequence of the sequence shown in each figure. It should be also noted that, each block in each block diagram and/or each flowchart, and combinations of the blocks in each block diagram and/or each flowchart, may be implemented on the basis of a hardware system for a specific purpose or perform specific functions or operations by means of the combination of hardware and computer instructions for a specific purpose.

FIG. 2 is a block diagram of the hardware environment of an illustrative client computer 202 according to the present invention. According to the present invention, a client computer is an electronic product which executes an application for providing instant messages, emails, short messages or any other application for transmitting data, including a desktop computer, notebook computer, terminal apparatus, mobile phone, or PDA. The client computer executes applications pertaining to word processing services or browsers. In an exemplary embodiment, the client computer is a universal desktop computer which comprises: a processor for executing various applications; a storage device for storing various information and code; a display device, a communication and input/output device, functioning as an interface for communication with the user; and a peripheral component or any other specific-purpose component. In another embodiment, the present invention is implemented in another manner and thus includes less or more other devices or components. A network is implemented in any form of connection, including a local area network (LAN) or wide area network (WAN) for use in fixed connection, or implemented in the form of dial-up Internet access gained through an Internet service provider, and is not restricted to various wired connections and various wireless connections. The network further comprises other hardware and software components (not shown), such as an additional computer system, a router, and a firewall.

The client computer 202 comprises a processor unit 204 coupled to a system bus 206. A video adapter 208 (which controls a display unit 210) is coupled to the system bus 206. The system bus 206 is coupled to an input/output (I/O) bus 214 through a bus bridge 212. An I/O interface 216 is coupled to the I/O bus 214. The I/O interface 216 communicates with each I/O device. The I/O devices include a keyboard 218, a mouse 220, a CD-ROM 222, a floppy disk 224, and a flash memory drive 226. Ports, which are connectable to the I/O interface 216, comply with one of port specifications well-known by persons skilled in the art on computer frameworks. The ports include, but are not limited to, a universal serial bus (USB) port.

With a network interface 230, the client computer 202 communicates with a service provider server 252 through a network 228. The network interface 230 is coupled to the system bus 206. The network 228 is an extranet (such as the Internet) or an intranet (such as Ethernet or a virtual personal network (VPN)). With the network 228, the client computer 202 accesses the service provider server 252 according to the present invention.

The network can also be implemented in any form of connection, including a local area network (LAN) or wide area network (WAN) for use in fixed connection, or implemented in the form of dial-up Internet access gained through an Internet service provider, and is not restricted to various wired connections and various wireless connections, for example, communicating with a computer device/system through a wireless network, such as GSM or Wi-Fi. The network further comprises other hardware and software components (not shown), such as an additional computer system, a router, and a firewall.

A hard disk drive interface 232 is coupled to the system bus 206. The hard disk drive interface 232 is connected to a hard disk drive 234. In a preferred embodiment, the hard disk drive 234 is populated with a system memory 236. The system memory 236 is coupled to the system bus 206. Data which populates the system memory 236 includes an application 244 and an operating system (OS) 238 of the client computer 202.

The OS 238 comprises a shell 240 and a core 242 whereby the user accesses resources, such as the application 244. The shell 240 is disposed between the user and an operating system and adapted to provide a program of an interface and an interpreter. The shell provides a system remind, interprets commands sent from a keyboard, mouse, or any other user input media, and sends to an appropriate low level (such as the core 242) of the operating system the interpreted commands for processing. Although the shell 240 is typically a text-based line-oriented user interface, the present invention can also support any other user interface modes, such as graphical mode, voice mode, and communicative motion mode. The core 242 comprises low-level functions of the OS 238. The low-level functions comprise basic services requested by the application 244 and the other portions of the OS 238. The basic services include memory management, process and task management, disk management, and mouse & keyboard management.

The application 244 comprises a browser 246. The browser 246 comprises program modules and instructions. The program modules and instructions comply with the HyperText Transfer Protocol (HTTP) whereby a client (i.e., the client computer 202) of the World Wide Web (WWW) sends/receives network messages to/from the Internet, thereby effectuating communication with the service provider server 252. The application 244 further comprises a tab tracking module 248. The tab tracking module 248 is implemented in the form of a daemon or a plug-in of the browser 246. In another embodiment, the tab tracking module 248 is implemented in the form of any other program. The tab tracking module 248 comprises code 250 for executing a program depicted in FIG. 5. In an embodiment, the client computer 202 downloads selected webpages through the service provider server 252.

In another embodiment, from the perspective of a framework and components, the client computer 202 can be a universal computer device, such as a personal computer (desktop computer or notebook computer), server, or information appliance, such as IBM WebSphere Datapower SOA Appliance or Tivoli ISS Appliances (“IBM,” “WebSphere,” and “Tivoli” are registered trademarks of International Business Machine in the United States and/or any other countries.) Furthermore, the client computer 202 can also be a mobile computation device, such as a smartphone, tablet, or personal digital assistant (PDA). A data input module of the smartphone and a display screen are integrated to form a touchscreen whereby the user creates data or inputs instructions.

The hardware components disposed in the client computer 202 as shown in FIG. 2 show essential components in the present invention in an illustrative rather than comprehensive manner. For instance, the client computer 202 can further comprise alternative memory storage devices, such as a magnetic cassette, digital versatile disc (DVD), Bernoulli Box, and the like. The above and other changes can be made to the present invention without departing from the spirit and scope of the present invention.

The present invention is hereunder further illustrated with one embodiment of a tab tracking module, which is not restrictive of the present invention as appreciated by skilled persons in the art.

The present invention provides a novel and intuitive way for visually reminding users about webpage information of a parent tab associated with a new child tab as well as specifying, by coloring or any visually identifiable manner, a parent link in a parent webpage of a parent tab, where the parent link has been previously clicked for the creation of a new tab.

FIG. 5 is a flowchart of a method for use with a tab tracking module 248 according to embodiments of the present invention. FIG. 5 is further illustrated by FIG. 3 that is a frame of a webpage on a browser display interface according to one embodiment of the present invention.

Step 502 opens a link from a parent webpage of a parent tab for identifying a new tab of a new webpage, in response to a click by a user on a link in the parent webpage of the parent tab. For example, after conducting a web search, the user clicks on multiple links in a resultant webpage obtained from the search, which opens the multiple links and enables viewing the multiple webpages intended to be visited. Thus, step 502 comprises receiving a click on one or more links included in a parent webpage being displayed on a graphical user interface (GUI) on which a parent tab associated with the parent webpage is displayed.

Step 504 creates the new tab when the link is open and displays the new tab on the GUI and/or replaces the parent webpage of the parent tab with the new webpage of the new tab.

Step 506 records the position and a width/height of the link.

Step 508 captures a screen of the parent webpage 102 to generate a screenshot, by triggering a snapshot mechanism.

Step 510 visually highlights the clicked link in the screenshot. In one embodiment, the link is circled by a slender frame, such as a slender frame 116 shown in FIG. 3. Any other suitable way enabling the link to be visually highlighted is applicable according to the present invention; for example, the links can be highlighted with a differentiated color or font.

Step 512 saves the screenshot with the highlighted link to a tooltip attribute of the new tab.

As shown in FIG. 3, step 514 detects the cursor 109 of a pointing device (e.g., a mouse) of a user hovering above the active new tab 106 and in response, step 516 retrieves the screenshot from the tooltip attribute and displays to the user on the GUI the screenshot 102′ having the highlighted link 116. The screenshot was created in step 508 by the capture of the screen of the parent webpage. Thus, the user can easily track webpage information of the parent tab associated with the new tab.

Step 518 receives, while the screenshot is being displayed, a click on the screenshot and in response, the parent webpage is reopened in the GUI.

In one embodiment, the screenshot 102′ is configured to cover the window totally or cover the window in part as shown in FIG. 3, and is even configured to integrate with scroll bar functionality. Alternatively, even if the webpage of the parent tab has been closed, the webpage of the parent tab can be re-opened by clicking on the screenshot to load the parent URL.

Illustrative code for the steps of FIG. 5 is as follows:

// when user clicks a link function click_event_fired (object domElement){  int ele_height = domElement.offsetHeight;  int ele_width = domElement.ofsetWidth;  //get position  var client_x = 0;  var client_y = 0;  while( domElement!= null){   client_y += domElement.offsetTop;   client_x += domElement.offsetLeft;   domElement = domElement.offsetParent;  }  // capture screen  capturePage_drawRect(window, domElement, thisFilename, client_x, client_y, ele_width, ele_height);  tabImageMapping[thisTabId] = thisFilename; } // function to capture a page and draw rectangle function capturePage_drawRect(window, myElement, filename. x, y, eleWidth, eleHeight) {  var grabber = {   prepareCanvas: function(width, height) {    var styleWidth = width + ‘px’;    var styleHeight = height + ‘px’;    var grabCanvas = document.getElementById(‘screenshot_canvas’);    if (!grabCanvas) {     // create the canvas     vas ns = ‘http://www.w3.org/1999/xhtml’;     grabCanvas = document.createElementNS(ns, ‘html:canvas’);     grabCanvas.id = ‘screenshot_canvas’;     grabCanvas.style.display = ‘none’;     document.documentElement.appendNew child(grabCanvas);    }    grabCanvas.width = width;    grabCanvas.style.width = styleWidth;    grabCanyas.style.maxWidth = styleWidth;    grabCanvas.height = height;    grabCanvas.style.height = styleHeight;    grabCanvas.style.maxHeight = styleHeight;    return grabCanvas; },  prepareContext: function(canvas, box) {   var context = canvas.getContext(‘2d’);   context.clearRect(box.x, box.y, box.width, box.height);   context.save( );   return context;  } }; var SGNsUtils = {  dataUrlToBinaryInputStream: function(dataUrl) {   var nsIoService = Components.classes[“@mozilla.org/network/io-service;1”]    .getService(Components.interfaces.nsIIOService);   var channel = nsIoService    .newChannelFromURI(nsIoService.newURI(dataUrl, null, null));   var binaryInputStream = Components.classes[“@mozilla.org/binaryinputstrearm;1”]    .createInstance(Components.interfaces.nsIBinaryInputStream);   binaryInputStream.setInputStream(channel.open( ));   return binaryInputStream;  },  newFileOutputStream: function(nsFile) {   var writeFlag = 0x02; // write only   var createFlag = 0x08; // create   var truncateFlag = 0x20; // truncate   var fileOutputStream = Components.classes[“@mozilla.org/network/file-output-stream;1”]    .createInstance(Components.interfaces.nsIFileOutputStream);   fileOutputStream.init(nsFile,     writeFlag | createFlag | truncateFlag,     0664,     null);   return fileOutputStream;  },  writeBinaryInputStreamToFileOutputStream:   function(binaryInputStream, fileOutputStream) {   var numBytes = binaryInputStream.available( );   var bytes = binaryInputStream.readBytes(numBytes);   fileOutputStream.write(bytes, numBytes);  } }; var doc = window.document.documentElement; var box;    box = {    x: 0,    y: 0,    width: doc.scrollWidth,    height: doc.scrollHeight    }; var originalBackground = doc.style.background; // grab var format = ‘png’; var canvas = grabber.prepareCanvas(box.width, box.height); var context = grabber.prepareContext(canvas, box); context.drawWindow(window, box.x, box.y, box.width, box.height,  ‘rgb(0, 0, 0)’); context.restore( ); // draw square context.beginPath( ); context.lineWidth=“6”; context.strokeStyle=“red”; context.rect(x,y,eleWidth,eleHeight); context.fill( ); var dataUrl = canvas.toDataURL(“image/” + format); // save to file var nsFile = Components.classes[“@mozilla.org/file/local;1”]  .createInstance(Components.interfaces.nsILocalFile); try {  nsFile.initWithPath(filename); } catch (e) {  if (/NS_ERROR_FILE_UNRECOGNIZED_PATH/.test(e.message)) {   // try using the opposite file separator   if (filename.indexOf(‘/’) != −1) {    filename = filename.replace(/V/g, ‘\\’);   }   else {    filename = filename.replace(∧Vg, ‘/’);   }   nsFile.initWithPath(filename);  }  else {   throw e;  } } var binaryInputStream = SGNsUtils.dataUrlToBinaryInputStream(dataUrl); var fileOutputStream = SGNsUtils.newFileOutputStream(nsFile); SGNsUtils,writeBinaryInputStreamToFileOutputStream(binaryInputStream,  fileOutputStream);  fileOutputStream.close( ); };

FIG. 4 is a frame of a webpage on the browser display interface according to one embodiment of the present invention. Step 510 in FIG. 5 comprises enabling all links being clicked in the same parent webpage of the parent tab 102 to be highlighted in the screenshot. Step 510 further comprises enabling the links to correspond each different tab by visually distinguishing the different tabs. Referring to FIG. 4, the links 414, 416, 418 are circled by slender frames in different colors that correspond to tabs 404, 406, 408 having corresponding colors, respectively.

A computer program product of the present invention comprises a computer readable hardware storage device having computer readable program code stored therein, said program code containing instructions executable by a processor of a computer system to implement the methods of the present invention.

A computer system of the present invention comprises a processor, a memory, and a computer readable hardware storage device, said storage device containing program code executable by the processor via the memory to implement the methods of the present invention.
